OVERVIEW

1.2 FEATURES

The following is a summary of your MP20’s features:

? FET, Class A Discrete Input Buffers. Each channel of

your MP20 contains a Class A discrete input buffer

followed by a dual servo gain stage. This provides ultra

low noise and wide gain control. This allows the MP20

user to boost desirable signal without increasing

unwanted background noise (NO capacitors!)

? 48 Volt Phantom Power. Each channel of the MP20 has

48V Phantom power available. When the Phantom

power switch is engaged, power is supplied at a constant

rate whether one or both channels are utilized. This

assures optimum performance of your condenser

microphone(s) and that it will be free of distortion

associated with insufficient power.

? Polarity Reverse. A phase reverse switch is provided on

each channel. This switch enables the user to invert the

phase of a microphone when phase cancellation is noted.

The phase reverse switch allows the operator to avoid

phase cancellation when identical microphones are used

in close proximity to one another. The phase reverse

switch also can compensate for different XLR connector

hook-ups where pin connections have been inverted.

? 20 dB Pad. A 20 dB pad is available on each channel for

reducing the in-coming signal level. This pad provides a

more manageable signal from high output devices giving

the operator greater control over the in-coming signal and

a much reduced chance of over-driving the input and

thereby avoiding distortion.

? +28 dB Headroom. The MP20 has +28 dBu of

1 2 3 4 5 6 7 8 9 10 ... 16 17
